Does it get that cold in the Tampa Bay area?

water plus a wetting agent like water wetter or purple ice.

and yes, sometimes water freezes in florida. I think it was the 2010 january nationals at sebring where ice was on the ground well into saturday morning. all of the citrus crops on the roads around the track were ice-covered too. they do that to protect the fruit from the cold...

During the driver school at RRR we were working in 2008 we actually had to drain some of the water/additive mixture to work in just a touch of anti-freeze. knowing nothing of winter-izing a car (all florida guys). We ran teh cars to work mix the anti-freeze in. Parked them inside the trailer, and left the radiator cap off.

It snowed that night and when we returned we could tell that a considerable amount of water was pushed out the radiator fill neck. I doubt that people up north have to go through this (there has to be an easier/better way), but I can only assume that the expansion of water when it started to freeze in the radiator pushed the water out and saved us from having to repair something in the morning.

Anti-freeze for me.

Too cold at many races to be foolin' around with just water or non-glycol additives.
